TanStack Security Postmortem

TL;DR

A brutal breakdown of how a major dev ecosystem got owned by a supply-chain attack and what they're doing to stop it from happening again.

Who is this actually for?

Frontend developers who blindly trust their npm dependencies and engineering leads trying to avoid a similar PR nightmare.

The Good

• Offers a transparent, technical look at how these attacks actually happen in the wild.
• Provides actionable lessons on CI/CD secret management and 2FA requirements.

The Catch (Potential Downsides)

It is a reactive document, not a tool that fixes your code. It also serves as a grim reminder of how fragile the modern JS ecosystem remains.
